Yes, and even for the ununionized ones, say meat packing facilities, they can get their boss for a word or go to the can when needed. Meat packers and other line jobs have a lot of problems that I've heard about but bathroom breaks and talking to ones bosses would be novel problems to me for those jobs.
Last Week Tonight recently did a show on the meat packing industry. The lack of bathroom breaks was specifically mentioned. https://youtu.be/IhO1FcjDMV4
TIL. Thanks for correcting me on that. Does America need to regulate bathroom breaks to deter companies from behaving like psychopaths or can they figure it out on their own and find some humanity?
